If you own an Intel Z170 or Z270 chipset motherboard, you may think it only supports up to 7th gen CPUs. But with some Kapton tape fixes and BIOS mods, you can actually make an 8th or 9th gen Coffee Lake CPU work on your board in a process known as “Coffee Mod”. This contrasts with AMD’s better support for older CPUs on Ryzen motherboards. While Intel may have intentionally introduced this incompatibility, users are finding ways to take back control of their platforms. However, newer security features like Intel BootGuard may hinder future mods. Thanks to [Lexi] for sharing this info!
